2 Outline Czech HEP Community and Contributions to Experiments Scientific Network and Computing Grid in the Czech Republic Plans Conclusion

3 Czech HEP Community High Energy and Nuclear Physics Community – 156 people 59 physicists 22 engineers 21 technicians 54 undergraduate and Ph.D. students Main HEP Collaborating Institutions –Academy of Sciences of the Czech Republic –Charles University in Prague –Czech Technical University in Prague –Masaryk University in Brno –Brno University of Technology –Technical University of Liberec –Silesian University in Opava –… Main HEP Institutions app. 500 km

4 Contributions to HEP and NP Experiments Past experiments –DELPHI, NA4, OMEGA, UA4-2, NA45, NA57, PIXEL(RD-19), GAS Microstrips (RD-28), TILECAL (RD-34), ROSE (RD-48), RADTOL (RD- 49) Current experiments –ATLAS, ALICE, TOTEM, AUGER – D0, H1, STAR –COMPASS (NA58), DIRAC (PS212), ISOLDE/IS381, RADHARD (RD50), nTOF, NEG, MEDIPIX –HADES and CMB (GSI Darmstadt), Cyclotron U-120M in NPI (max 40 MeV protons) –ENLIGHT (hadron therapy) Detector development –Silicon pixels and strips, calorimeters, crystals, electronics Computing –EDG, EGEE, EGEEII, WLCG Theory

5 Czech Scientific Computer Network CESNET –Czech National Research and Education Network provider –Association of legal entities formed by all universities of the Czech Republic and the Academy of Sciences of the Czech Republic –Operation and development of the Czech NREN (CESNET2 network) –Research and development of advanced network technologies and applications

6 CESNET2 topology

7 GEANT2 planned topology May 2006

8 1 Gbps lines to -FNAL -TAIPEI -FZK (very new) Optical 1 Gbps connections with collaborating institutions in Prague Optical network infrastructure Provided by CESNET for HEP TIER2 farm GOLIAS

9 GRID Computing Pre – GRID experience from 90 th –METACentrum project of CESNET Interconnection of supercomputers at Czech Universities AFS, single login and common job submission, user support, application SW 400 linux processors + few special “supercomputers” GRID-like project No real national GRID project Participation to international GRID projects via CESNET METACentrum project –EDG (from 2001), EGEE, EGEEII –GRIDLAB, CoreGRID –WLCG (from 2002)

10 High Energy Physics WLCG GRID WLCG Tier 2 centre Two separate farms –CESNET_EGEE – farm SKURUT located at CESNET 30 processors, storage on GOLIAS, used for ATLAS Part of CE ROC, support of VOCE –Prague – farm GOLIAS located at FZU (Institute of Physics ASCR) SKURUT

11 Prague T2 center Prague – GOLIAS from 2004 –Heterogeneous hardware, due to irregular HW upgrades (from 2002) –total 121 nodes (including Blade servers), 250 cores –~150k SpecInt2000 GOLIAS

12 Prague T2 center –41 TB of raw disk space; 3 disk arrays 1 TB array (RAID 5) 10 TB array (RAID 5) 30 TB array (RAID 6) –Tasks 150/100 D0/LHC –Network Connections 1 Gbps lines GEANT standard infrastructure FNAL, p2p, CzechLight/GLIF Taipei, p2p, CzechLight/GLIF FZK Karlsruhe, p2p over GN2, from 1 September 2006 –150 kW total electric power for computing, UPS, Diesel

13 Personnel 4 persons to run WLCG Tier-2 –Jiri Kosina – middleware, Storage (FTS), monitoring –Tomas Kouba – middleware, monitoring –Jan Svec – basic HW, OS, storage, networking, monitoring –Lukas Fiala - basic HW, networking, web services –Jiri Chudoba – liaison to ATLAS and ALICE, running the jobs and reporting errors, service monitoring (more personnel on EGEEII)

14 Supported VOs: ATLAS, ALICE D0 STAR, AUGER, HONE Contribution to D0, ATLAS-LCG, ALICE on the level 5-9% in 2005 On graph: Alice VOBOX problem stopped Alice jobs submission (pink colour)

15 SERVICE CHALLENGE 2006 FTS tests FZK - FZU FZK – FZU, standard GEANT internet connection Transfer of 100 files, each file 1GB FZU – SARA, standard GEANT internet connection Transfer of 50 GB J. Chudoba 48 MB/s

16 Service planning ATLAS + ALICE CPU (MSI2000) Disk (TB) MSS (TB) Table based on WLCG TDR for ATLAS and Alice and our anticipated share in the LHC experiments We submit project proposals to various grant systems in the Czech Republic Prepare bigger project proposal for CZ GRID together with CESNET –For the LHC needs –In 2010 add 3x more capacity for Czech non-HEP scientists, financed from state resources and structural funds of EU All proposals include new personnel (up to 10 new persons) No resources for LHC computing, yet Proposed plan for WLCG Grid resources in the Czech Republic

17 Conclusion GRID for HEP in the Czech Republic –Has good grounds to be built-up Excellent networking Existing infrastructure of specialists contributing to international GRID projects Pilot installation exists and is fully integrated into WLCG/EGEE and can be enlarged –Projects proposals for HEP GRID regularly proposing National GRID proposal (with CESNET) prepared –No adequate financial resources for GRID infrastructure, yet
